Patented Sept. 3, 1918.

Application filed: September 22, 1911. Serial No. 850,695.

To all whom it may concern:

Be it known that I, J onx L. Cnsvsuxc, a resident of Sew York, in the county and State "of New York, have invented certain new and useful Improvements in Electric n I v ble to systems of electric distribut on wheretranslating devices, it will be described inconnection with such a system.

tation of one type of system embodying the essentials of my invention. r

In the drawing, 1 represents a dynamo or generator provided with the usual field coil 2 having in series therewith resistances 3 and 1 indicated as of the carbon pile variety, and it will be obvious that the dynamo may he regulated by proper manipulation of the resistances 3 or 4. The resistance 3 is controlled by the .lever 5 normall drawn in an upward direction as by a justable spring 6 in such manner as to tend to com- 1 pr'essthe carbon pile 3 and lower thereextremity a core of magnetic material 7 and thus motion imparted to said core may serve sistance thereof. The lever 5 carries at one i to regulate the generator. The resistance 4 is controlled by the lever 8 normall drawn 4d in an upward direction as by the a justable press the carbon spring 9 in such manner as to tend to comile 4 and lower the resistance thereof.. T e lever B isproy-"lded at ohe extremitv with a core 10 of magnetic material and thus the generator may be reg represents the positive lead of the generator which is carried to one side of the switch 12.

. which is preferably of the automatic va- \-oltage of the generator is substantially that of the battery and as many such switches are known in the art and'the parerator.

From the switch 12 the lead 11 continues to one sidt of the switch 13 and is connected with tlietpositive side of the storage battery 1 the negative side of which is connected as by wire 15 with one end of the coil 16 surrounding the core 7 and having its other terminal connected as" by lead 17 to the negative brush of the gen- From the switch 13 the wire 18 is carried to-one side of the lamps or other translating devices 19 having their negative terminals connected with the wire 20 which is carried to'oneside of a translation circuit regulator; in this instance indicated as .a carbon pile 21 having its opposite ter- 'minal connected as by wire 22 with the coil 23, the opposite end of which is in connection with'the lead 17. .Thecoils 16 and 23 are so woundthat if either'be alone energized the same will tend to draw the core 7. downwardly against the action of spring 6 and increase. the resistance 3, and so wound that current passing through the coil-'16 when the tery-.is being char ed will set up a; magn' motiveforce int same directio'n-asithat up by the coil: 23 when we lamps or fianslatingdevices tothe battery. 24 is a coil in shunt across the neratoncirtherethrough: from the:
